Like this, first vertical portion and the discharge tube 12 intercommunication of accepting the glass liquid for introduce the glass liquid, first kink is used for changing the flow direction of glass liquid and introduces the glass liquid into rotatory pipeline 2, and the glass liquid in the rotatory pipeline 2 further flows into the second kink, and the flow direction of glass liquid is further changed to the second kink to draw forth to the mouth 13 that gathers materials through second vertical portion finally.

In the present embodiment, the first pipeline 1 is formed with the first vertical portion and the first bent portion through the hot bending process, and the second pipeline 3 is formed with the second vertical portion and the second bent portion through the hot bending process.

Therefore, the hot bending process is simple and convenient to operate, and bending at different angles can be performed according to requirements.

In this embodiment, the first duct 1, the second duct 3, the rotary duct 2, and the discharge duct 12 are made of 310S stainless steel, and the shield 14 is made of 304 heat-resistant steel.

Example two: the difference from the first embodiment is that the wall thickness of the first pipe 1, the second pipe 3 and the rotary pipe 2 is 10 mm.

Therefore, the service lives and the service costs of the first pipeline 1, the second pipeline 3 and the rotary pipeline 2 can be taken into consideration, and the problems that the service cost is increased due to the fact that the wall thickness of each pipeline is too thick and the service life is reduced due to the fact that the wall thickness of each pipeline is too thin are solved.

Example three: the difference from the first embodiment is that the first bearing 8 has an outer diameter which is 5mm smaller than the inner diameter of the corresponding rotary pipe 2 and the second bearing 9 has an inner diameter which is 5mm larger than the outer diameter of the second nested extension of the corresponding rotary pipe 2.

Therefore, the convenience of dismounting the rotary pipeline 2 and the stable and reliable performance of the connection between the first bearing 8 and the second bearing 9 and the rotary pipeline 2 at the corresponding positions can be both considered.

Example three: the difference from the first embodiment is that the first bearing 8 and the second bearing 9 are both cylindrical roller bearings.

Therefore, the cylindrical roller bearing can bear certain impact load, and the use performance is stable and reliable.
